The inet_network() routine converts a string representing an Internet address (for example, ``127.0.0.1'') into a numeric Internet network.
All Internet addresses are returned in network order (bytes are ordered from left to right). All network numbers and local address parts are returned as machine-format integer values. For more information on Internet addresses, see inet_aton().
